Sorry, but NAK. You seem to be doing a mechanical code change without
first understanding the code, as the patch shows no sign of an
understanding of the difference between phy_modify() and __phy_modify().
This means you are introducing new bugs with this change.

Please investigate the differences between the two variants of
phy_modify() and post a more correct patch.

Thanks.
